Hello, I wonder if anyone can give me some pointers / advice please ? Basically I've recently bought a second hand Audi A3 (51 plate - 66,000 miles) and it's been running fine for the last couple of months, although there was a coolant leak when I bought it so this was fixed as it was due to some problem with the radiator or pump or something (apologies, but I'm not technical as far as cars are concerned!) Anyway, I've suddenly noticed oil patches on the driveway so it looks as though there is a problem there. Also, the coolant warning light has started coming on the dashboard and the temperature gauge shows 120 once i've been driving for about 10 minutes. I've topped up the coolant as it was showing under the minimum, but the next day, the same thing happened. What is likely to be the cause of this ? Is it serious ? I'd appreciate any advice anyone can offer. Thank you.
